State of the Art Materials

Gypsum is a natural mineral mined throughout the world. Glass Fiber Reinforced Gypsum (GFRG) is comprised of a mixture of raw gypsum and cement, laminated to layers of long strand, continuous glass fiber matting.

GFRC is a cement-based composite, reinforced with glass fiber. Fibers are usually used in concrete to control plastic shrinkage cracking and drying shrinkage cracking. They also lower the permeability of concrete and thus reduce bleeding of water.
